Amazon.com’s Sunday delivery program is now available in 15 additional cities, beyond the New York and Los Angeles metro areas where the program originally launched last November, the online retailer announced Thursday.

Amazon Prime members who order an eligible item as late as Friday can receive the package — delivered by the U.S. Postal Service — as soon as Sunday, under the two-day shipping benefit that comes with the $99 annual Prime membership.

The additional markets: Austin, Cincinnati, College Station, Tx., Columbus, Dallas, Houston, Indianapolis, Lexington, Ky, Louisville, New Orleans, Oklahoma City, Philadelphia, San Antonio, Shreveport, and Waco, Texas. Amazon plans to roll out the program to more of the U.S. population during the year.

Amazon says “millions” of products qualify for Sunday delivery. “So far, the most common items delivered on Sunday include baby supplies such as newborn apparel, books and toys — Sunday delivery is clearly crossing errands off the weekend to-do list,” said Mike Roth, Amazon’s vice president of North America operations.

If a purchased item is available for Sunday delivery in a given region, consumers will see that option when they add the item to their shopping carts during checkout.
